CONDUIT CONSTRUCTION.

. Application flled January 18, 1925. Serial No. 2,704.

The present invention relates to a construction for the housing andprotection of underground pipes conveying steam, water,-

air, and other materials, and the purpose of the invention is to providea construction wherein co-operating pipe sections are mountedu n asuitable base comprising separate umts which are arranged as a support,and assist in the drainage of the ground surrounding the pipe sections bforming a conduit for carrymg awa'y t e drainage water. A

A further object of the invention is to provide pipe sections which aremade in imy particular manner for the purpose of securing a structurewhich permits the mounting of the conduit pipes upon the base members,

em in proper position with respect to each other.

Reference should be had to the accoinpanying drawings forming a -partofth1s. specification, in which Fig. 1 is a side elevat1on showing'co-operating drain pipes and base sections; Fig. 2 is a sectionalelevation; Fig. 3 is a bottoni plan view of a pi e section; Fig. 4 is atop plan view of a h f ipe section; Fig. 5 is an end elevation of a alfpipe. section and a base section; Fig. 6 is an end elevation ofco-operating parts of a pipe and a base which is shown in section.

Referring to the drawings. 1 indicates sections Of a base mount' whichalso serves as a drain conduit. Each ase section is hollow from end toend so that when the base sections are arranged end to end as in Fig. 1,the hollow interior portions are in alignment and constitute' a drainageconduit. In assembling the members 1 withrespect to each other they arespad a slight distance apart at their abutting ends, which permitsdrainage water to enter between ad'aeent base members 1 and flow throught e interior thereof.

Each section 1 of the base is provided w1th a fiat bottom ortionwhich isadapted to be seated upon afied prepared for tire same, and the u persurface 13 rounded, as 1nd1catd at 2, and at each of the opposite edgeson the top portion there is a slight upstandmg baud, as indicated at 3upon which -bead the conduit sections rest, as will later ha described.-By virtue 'of the fact that the two parallel ridges or .beads 3 areprovided, tige conduit is supported u n these beads, and 13 therebygiven two pomts of support which will provide a uniform supportthroughout the length of each conduit.

The conduits proper are formed each with two cO-operating sections,which are indicated at 4 and 5. These conduit sections when assembledwith respect to each other prov1de substantially a bell and spigotconduit. The lower section 4 of each conduit 1s provided with a bellsection 4 at one end, and through each bell section there is an openmghaving parallel sides, as indicated at 4", which is substantially thewidth betweep the outside side walls of a base mountmg Therefore, aswill be seen froni Figs. 5

and 6, when a lower section 4 is placed upon a base section, thecylindrical bod portion W111 co-operate with the rid es 3 0 the basemember, as before describe while the bell portion will straddle the topof the base port1on. Thls structure prevents any tendency fo r turningor rotary movement of the section 4 when mounted upon the base portion1.

Additionally, the construction for the section 4 of the conduitdescribed obviates the necessity cf providing any means, such as an 0enin or slot in the base members l, whic wou d otherwise be required toaccommodate the bell end of each conduit section.

The section 5 of each conduit section has a semi-cylindrical bodyportion with a bell end 5" which co-operates with a section 4 forming acompleted conduit when the two parts thereof are assembled.

The succeeding sections of the conduit are assembled b the co-operationof the bell end of each con uit member with the spigot end of anadjacent conduit member.

Having described our invention, we claim:

1. An underground conduit construction comprising a conduit cOmposed ofa plurality of abutting pipe sections, a plurality of base membersarranged beneath said conduit sections for supporting the same, each ofsaid conduit sections bein provided with a notched out portion whichstraddles the upper portion of a base section upon which it reste.

2. An underground conduit construction cornprising a conduit composed ofa plurality o abutting sections with interfitting ends, a plurality ofbase members arranged beneath said conduit sections and sup orting thesame, each of said conduit sections et one end thereof havin a. notchedont portion which straddles t e upper part of the base member upon whichit tests.

3. An underground conduit construction comprising a plurality et conduitsections arran ed end to end each section having a bell ormation at oneend receiving the spigot end of an adjacent section the bell section ofeach conduit being provided with a. notched ont portion adapted tostraddlc the upper part of a base member with which it co-operates.

4. An underground conduit construction comprising a plurality ofabutting conduit sections each of said conduit sections being formed intwo halves, a plurality of aligned base members beneath the said conduitsections and supportin the same, the lower portion'of each con uitsection being provided with a notch adapted to straddle the top of abase member with which it co-operates.

5. Anunderground conduit construction comprising a plurality of conduitsections i arranged end to end, each of the said conduit sections havinga bell formation at a slot which is adapted to straddle the top of abase section with which-it co-operates. 6. An underground conduitconstruction comprising a. wnduit composed of a plurality of abuttingconduit sections each section having a bell end and a spigot end, aplurality of base members arranged beneath the conduit sections forsup'porting the same, each of said base members having two parallelridges upon which the conduit sections rest each conduit section havingthe bell portien provided with a slot adapted to straddle the upperportion of a base member with Which it co-operates.

In testimony whereof, we hereunto afiix our signatures.
